CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 412,879,-dated October 15, 1889..

Application filed May 14, 1889. Serial No. 310,728. (No model.)

To aZZ whom it may concern:

Be it known that we, ABRAHAM DEYO and WILLIAM S. SGHROEDER,citizens of the United vation, the sectional part being in plane 1,

Fig. 2, lengthwise of. the draw-bar, showing the head end and coupling-hook in elevation, looking in the direction indicated by the arrow; and Fig. 2, a horizontal longitudinal section.

Referring to the drawings, A represents the draw-bar; B, the head or enlarged end;

C, the coupling hook, and O the pivot-pin securing the hook O to the head end of the draw-bar. The locking-lever D is arranged longitudinally in the chamber D of the drawbar, and is provided vertically with the elongated aperture a, for the insertion of the pin or bolt a, which passes through the top and bottom of the draw-bar and secures the locking-lever in proper relative position with reference to the draw-bar and coupling-hook. The lugs a a formed on and projecting inwardly from the side or cheek a of the drawbar, provide against a lateral movement of the locking-lever. The inside bottom of the draw-bar is provided with the raised rounded seating-surface b. By this arrangement the locking-lever is adapted to have a rocking movement in a vertical plane.

To the rear end of thelever D is connected the inner upper end of the link Z), the lower end of which projects through the opening b in the under side of the draw-bar, as shown in Fig. 1. The projecting end of the link I) is provided with the aperture b for the attachment of any suitable means extending inwardly from both sides of the car, whereby The inner end of the coupling-hook is provided with the beveled surface I), onwhich the outer or looking end of the lever D rides when the coupling-hook swings on its pivot in the act of uncoupling. Normally the locking end of the lever D lies in the pathway of the inner end of the coupling-hook, which moves in the plane of a circle.

The head of the draw-bar is provided at one side with the chamber (1, in which is seated the coiled spring at, bearing against the back edge of the coupling-hook, and serves the purpose of automatically throwing the inner end of the hook outwardly when the locking end of the lever is raised, and thereby conveniently disengaging the companion hooks.

hen companion coupling-hooks are made to engage or interlock, the outer end of the lever D automaticallyv drops down into the locking position and prevents the coupling-hooks from being accidentally thrown out of engagement. The outer end of the hook has the aperture d and the recess d which provide for coupling with a drawbar having the ordinary link and pin.

Having thus described our invention, what We claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the draw-bar, of the locking-lever chambered therein and provided near the back end with an elongated aperture, the pivot-pin passing through said aperture and the link secured to said lever and projecting through the under side of the draw-bar, substantially as and for the purpose set forth.

2. The combination, wit 11 the draw-bar provided on the inside with the raised rounded seat and inwardly-projecting lugs, of the locking-lever chambered in said draw-bar, whereby said lever is adapted to have a rocking movement in a vertical plane, but prevented from moving laterally, substantially as and for the purpose set forth.
